2 Claims.

This invention relates to improvements in combination oil and gas rangesand has for its principal object to provide a flue system which willgreatly increase the oven heating capacity and efiiciency of the hot airand gases circulating therethrough.

Other objects and advantages of the invention will be understood as thedescription is conwhich Figure 1 is a top plan view of a stove embodyingthe invention;

Figure 2 is a front elevation of the stove shown in Figure 1;

Figure 3 is a fragmentary view taken on the line 3-3 of Figure 2illustrating the bypass for direct exhaust of gases to the flue duringinitial heating of the oven;

Figure 4: is a partial end elevation; Figure 5 is a section on the lineLt of Figure 1; and

Figure 6 is a section on the line t--fi of Figure 5.

Referring more particularly to the drawings, i denotes a combination oiland gas range comprising iront and rear walls t and 3, side or end wallst and 5 and a top t. The range is provided with the usual top gasburners i, four in number, arranged within a burner compartment 18,beneath the burner openings i in the top wall 6, grids 9 being seated inthese openings. The compartment 8 extends above and is spaced from. thetop wall iii of an oven it, thus forming an upper space between itsbottom wall and the top wall of the oven extending across the top of theoven for the passage of the hot air and gases. This space is subdividedinto two top passages or ducts i3 and it by a vertically disposedpartition wall IS. The top burners are controlled by valves l2, and gasis supplied to the burners from a manifold, not shown.

Suitably supportedin an ollburner compartheat from the oil burners ll.Drippings fromthe burners arev caught in a tray 21.

An oven gas burner 20' is located beneath the bottom wall of the ovenfor 'use in case it is not desirable to use the oil burners, or whereadditional' heat for the oven is required. This burner is located in abottom duct 2! formed by the. space between the bottom of the oven andthe bottom wall 22 of the range I, and receives gas from a. supply pipe28, connected with a manitold, not shown.

An opening 23, in the rear Wall 3 of the range, and positioned directlybeneath the top thereof, communicates with the upper end of a backconduit 2%, which extends downwardly at an angle along the rear wall 3and communicates at its lowerend with a bottom duct 2!. This duct M isalso in communication with the lower end of a vertically disposed sideduct or conduit 25 which in turn communicates at its upper end with theduct or space l3, previously described as occupying the space betweenthe top of the oven and the bottom of top gas burner box or compartment8. The duct 25 occupies the space between one side wall of the oven andthe side wall t of the range. Hot gases entering duct it from duct 25,escapes through an exit opening 26 formed in the back of the range andleading from the duct or space it to a stack or flue 3t.

When oil burners ii are initially lighted a sliding damper 29 normallyclosing openings 3i], in division wall i5 is manually opened by means ofa. rod 3!. This permits the hot expanding gases rising from the oilburner box or compartment Hi, to pass from the narrow top duct throughopenings 30 and across a. considerable top area of the oven beforeescaping to the flue. As a result the top of the oven is quickly heatedand this in turn creates a natural draft which causes the gases to flowin a manner about to be described, after the damper 29 has been closed.7

Assuming that oil burners ii are burning and that damper 29 has beenclosed after the initial operation just described, the hotgases will bedrawn downwardly through the duct 24 by the draft previously created. Asthe hot gases emerge from the lower end of duct 24 into bottom passageor duct 2i, extending underneath the oven H, a bafile plate .32 causesthe gases to sweep forwardly in a wide curving course before passingfrom the duct 2|, into the lower end of side duct 25, thus insuringcontact with and heating of the entire bottom area of the oven.. Fromthe right side of duct 2!, the direction of flow is upwardly throughduct 25 and thence in-y wardly through duct 13, where a bafile plat 33causes the gases to sweep across the top of th oven to andthrough flueopening. 26. r 1 I From the foregoing it will be seen that the hot gasescan be passed directly to the flue across a considerable top areaoi theoven, by opening the damper 29, and that after initially heating theoven and promoting a drait through opening 24 to the flue 34, the courseor the gas can be I changed to flow downwardly through the conduit 24 bythe shortest possible route, along the rear 01' the oven at one sidethereoi' and thence underneath the oven, and finally upwardly along theother side and over the top to the flue. The hottest gases thusreach bythe most direct and quickest route, the side of the oven remote from thefire box It and the bottom of the oven, the portions to which it isdesired to convey the greatest heat. While I have illustrated theconduit 24 as extending downwardly and to one side noted that by runningthe down draft flue or duct 24 directly down the back of the range, orsubstantially in that direction, then under the oven, up the back, endoi 'the range, then over the back section oi top into the outlet flue34, it is possible to locate the gas burner under the oven.

in the passage 2|, directly at the bottom oi. the down draft flue orduct 24. This flue 24, in addition to carrying heat from the oil burnersto the bottom of the oven, also furnishes the air for the oven gasburner 20'. In prior dual oven range constructions with which we arefamiliar, the gas burner is located in the oven through a well in thebottom of the oven, the air being furnished through this well. It isalso common practice to bring the primary air in through a tube. Thisnecessitates the use of a bailie plate in the bottom of the oven,whereas according to the present invention, this is unnecessary becauseample air is supplied to the gas burner through the flue 24.

.Having thus described my invention:

What I claim is:

' 1. A range comprising a casing, a fire box therein at one end, aheater in said fire box, an oven within the casing and in contact withthe fire box at one end, and having a passage across the top, a passageat one end and a passage across the bottom, said passages communicatingand forming a continuous passage, the upper passage communicating withthe fire box, a damper controlling the communication between the fireboxand upper passage, a flue communicating with the upper end of the firebox and extending diagonally downwardly and communicating with thebottom passage adjacent the fire box at one side and the upper passagecommunicating with a flue approximately midway its ends.

2. A range comprising a casing, a fire box therein at one end, a heaterin said fire box, an oven within the casing and in contact at one endwith the fire box and having a passage across the top, a passage at oneend Opposite the fire box .and a passage at the bottom forming acontinuous passage from the fire box under the bottom and around the endand across the top to and communicating with the fire box, a dampercontrolling the communication between the upper passage and the firebox, a down fiue communicating with the upper end of the fire box andextending diagonally downwardly and communicating with the bottompassage adjacent the tire box, a bame plate in the bottom passageintermediate its ends to cause a zigzag passage from the down flue tothe end passage and a flue connected to the upper passage approximatelymidway its ends.
